Adjustable barbecue grill

Abstract

The present grill has a food-support grid that is adjustable both vertically and rotatively. The vertical adjustment determines the spacing of the food being cooked above the charcoal or other heat source. The rotative adjustment enables the food to be positioned to one side of the charcoal or other heat source, for example, to provide a keep-warm mode for already-cooked food or a thawing mode for frozen food yet to be cooked.

I claim: 
     
       1. A grill comprising: a firebox having a bottom and a peripheral sidewall extending up from said bottom;   a post extending up from said bottom and spaced from said peripheral sidewall of the firebox;   a food-support grid slidably and rotatably mounted on said post;   a lower handle above said grid, and means rigidly coupling said lower handle to said grid so that said grid can be rotated on said post by turning said lower handle;   an upper handle above said lower handle;   and means for screw-threadedly raising and lowering said grid along said post in response to turning said upper handle.   
     
     
       2. A grill according to claim 1 and further comprising: a charcoal-support grate extending only part-way across the interior of said firebox below said food-support grid.   
     
     
       3. A grill according to claim 1 wherein said means for screw-threadedly raising and lowering said grid comprises: a shaft attached to and extending down from said upper handle and having screw-threads thereon;   a screw-threaded opening in said lower handle threadedly receiving said shaft;   a rounded lower end segment of said shaft below said lower handle;   and an upwardly-facing socket on the upper end of said post engaged by said lower end segment of said shaft.   
     
     
       4. A grill according to claim 3 and further comprising: a charcoal-support grate extending only part-way across the interior of said firebox below said food-support grid.   
     
     
       5. A grill comprising: a firebox having a bottom and a peripheral sidewall extending up from said bottom;   a post extending up from said bottom and spaced from said peripheral sidewall of the firebox, said post having an upwardly-facing socket at its upper end;   a food-support grid slidably and rotatably mounted on said post;   a lower handle above said grid and above the upper end of said post, and means rigidly coupling said lower handle to said grid so that said grid can be turned on said post by turning said lower handle and said grid can be slid up along said post by raising said lower handle, said lower handle having a screw-threaded opening therein aligned vertically with said socket in the upper end of said post;   an upper handle above said lower handle;   and a screw-threaded shaft connected to and extending down from said upper handle, said shaft being threadedly received in said opening in the lower handle and extending down through said lower handle to the upper end of said post, said shaft at its lower end being shaped complementary to said socket and rotatably engaging said post at said socket, whereby said lower handle and said grid are raised and lowered in response to turning said upper handle.   
     
     
       6. A grill according to claim 5 and further comprising: a charcoal-support grate extending only part-way across the interior of said firebox below said food-support grid.   
     
     
       7. A grill comprising: a firebox having a bottom and a peripheral sidewall extending up from said bottom;   a post extending up from said bottom and spaced from said peripheral sidewall of the firebox, said post having an upwardly-facing socket at its upper end;   a food-support grid slidably and rotatably mounted on said post, said grid being removable from said post by sliding said grid up along said post;   a lower handle above said grid and above the upper end of said post, and means rigidly coupling said lower handle to said grid so that said grid can be turned on said post by turning said lower handle and said grid can be slid up along said post by raising said lower handle, said lower handle having a screw-threaded opening therein aligned vertically with said socket in the upper end of said post;   an upper handle above said lower handle;   and a screw-threaded shaft connected to and extending down from said upper handle, said shaft being threadedly received in said opening in the lower handle and extending down through said lower handle to the upper end of said post, said shaft being screw-threadedly removable up through said lower handle, and said shaft at its lower end being shaped complementary to said socket and rotatably engaging said post at said socket, whereby said lower handle and said grid are raised and lowered in response to turning said upper handle.   
     
     
       8. A grill according to claim 7 and further comprising: a charcoal-support grate extending only part-way across the interior of said firebox below said food-support grid.
